You can use :
- NSConnection/NSPorts ( http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/articles/SocketComm.html#/
/apple_ref/doc/uid/TP40001479 )
- YAMessageQueue (10.4-): http://www.2pi.dk/tech/cocoa/message_queue.html
- NSOperation/NSOperationQueue (10.5+) :
- [NSObject performSelector:onThread]/[NSObject 
performSelectorInMainThread:] (10.5+);
